One thing worth exploring is to change the projection from Mercator to something like Albers Equal Area Conic projection (EPSG:9822).

It will reduce the size of Finnmark somewhat and bring it in line with the rest of the country. It can also be fun to experiment with some of the options.

Here are some AI suggestions, but I have no verified or tested it.

• Central Meridian: 15.0° E (Centers the projection along Norway's longitudinal axis).
• Standard Parallel 1: 59.0° N (Focuses on Southern Norway).
• Standard Parallel 2: 69.0° N (Focuses on Northern Norway).
• Latitude of Origin: 63.0° N (The approximate geographic center).
• False Easting: 0.0
• False Northing: 0.0
